Wireless Music Transfer iTunes?

Is there a way to transfer music from my library in iTunes to my iPad and iPhone, without having to connect them via USB cord? Thanks!

Not that i'm.aware of.

No. You can only do it using the USB cord that is supplied.

Yes.
Connect your device using the USB cable, Launch iTunes, select the iOS device from the sidebar, under "Summary" scroll down to find "Options" Check the box next to "Sync this (iDevice) over WI-FI", then select apply. You're good to go.
To transfer, all you have to do is drag and drop the songs onto the device in the sidebar.

You can use 4easysoft iPhone Manager, it supports to transfer files between iPhone and iPad.
